A new study revises the understanding of coelacanth fish anatomy, revealing that many previously thought evolutionary muscle features are actually ligaments, which reshapes our view of vertebrate skull evolution and shows coelacanths are more similar to sharks and tetrapods than previously believed.
The hingemouth, a small brown fish found in central west Africa, has a truly bizarre feeding apparatus that includes a trunk-like mouth that extends from its forehead to suck up food from the ground. Researchers spent five years investigating this unique mouth structure, which they named the proboscis, and found that it allows the hingemouth to thrive in its swampy habitat by breathing air and feeding on detritus. Despite its extreme anatomical reorganization, the hingemouth proves that evolution can lead to wild diversity beyond conventional notions of success.
